A drama with wasted potential and wasted actors, the first few episodes seemed very promising, a plot that deals with split personalities and childhood traumas, I thought I was going to see something like "Hyde Jekyll, Me (starring Hyun Bin)" or "It's Okay Not to Be Okay" or "Kill Me, Heal Me" (which were excellent dramas) As the episodes progressed, the cruelty also arrived, the whole plot went wrong into one big mess, there is no focus in the plot, I love and appreciate the actress Shin Hye Sun very much, and here too she demonstrated her professional and versatile abilities, but her acting alone cannot hold up the messy plot. The music was mediocre and there was a lot of background noise bordering on annoying. All in all, a plot that had tremendous potential and somewhere along the way it was wasted, such a shame
